IMPROVEMENT IN MECHANICAL MOVEMENTS.

Specification forming part of Letters Patent No. 187,473, dated February 20, 1877 application filed January 8, 1877. I

To all whom it may concern:

Be it known that I, GARRETT W. LOW, of Erie, Pennsylvania, have invented a new and useful Improvement in Mechanical Movements, which, improvement is fully set forth in the following specification, reference being had to the accompanying drawing.

The object of my invention is to impart a direct reciprocating motion to a piston-rod by means of a lever, whose fulcrum has a reciprocating movement given to it by an oscillating arm connecting with the lever between its fulcrum and the piston-rod.

Figure 1 is an elevation illustrating the invention.

Motion is given to the pistonrod b in the hollow cylinder at by means of the handle of the lever h. The fulcrum c of the lever his in the oscillating arm g, which turns on a pin in the standard 00, attached to the cylinder a. Between the fulcrum cand the piston-rod b, the lever h is connected with the oscillating arm 8, which turns on a pin in the standard a. The relative positions of the two oscillating arms 8 and g are such that when the lever h is at right angles to the piston-rod b, the arm 8 is parallel with the lever, and nearly at right angles to the arm 9, as shown in the drawing, and by turning the lever on its fulcrum the arm 8 moves the fulcrum 0 toward the pistonrod, so that the end of the lating arms s and g, and the piston-rod 11, substantialiy as and for the purpose herein set forth.
